In the plastics industry, particularly for materials like Polyethylene Terephthalate (PET) and Polycarbonate (PC), protection against ultraviolet (UV) radiation is crucial for maintaining material integrity and performance. NINGBO INNO PHARMCHEM CO.,LTD., a recognized manufacturer and supplier of advanced polymer additives, highlights Benzoxazinone UV Absorber 3638 as a key component for achieving superior UV stabilization in these versatile polymers. For R&D professionals and procurement managers, understanding the benefits of this specific UV absorber is essential when making purchasing decisions.

The Technical Edge of UV Absorber 3638 for PET and PC

UV Absorber 3638 is a high-performance benzoxazinone UV absorber. Its design offers a critical advantage: strong and broad absorption in the UV-A spectrum, alongside effective UVB protection, with no detrimental color contribution to the polymer. This feature is particularly important for PET and PC applications where transparency and optical properties are paramount, such as in films, sheets, and molded components. When manufacturers choose to buy UV Absorber 3638, they are investing in a product that preserves the aesthetic and functional qualities of their end products.

Furthermore, UV Absorber 3638 demonstrates excellent thermal stability, with a TGA of 371°C (10% loss). This high heat resistance is vital for PET and PC, which are often processed at elevated temperatures. The additive remains stable during these processes, ensuring consistent protection without degradation or loss of efficacy. This robust performance at high temperatures makes it an ideal choice for companies looking to buy additives that can withstand demanding manufacturing conditions.

Applications and Benefits for Manufacturers

For PET applications, UV Absorber 3638 is highly compatible, dissolving quickly and maintaining transparency even at higher concentrations. This makes it perfect for PET films, fibers, and containers that require significant UV shielding. In the case of Polycarbonate (PC) and PETG, it provides exceptional stabilization, enhancing their outdoor durability and preventing yellowing or embrittlement. The fact that it is FDA approved for food contact applications further broadens its utility, especially in packaging solutions.
